+Content : Simple sendrecv msg example
+Author : SimGrid Team
+====================================================
+
+
+This directory contains a simple send/recv example
+using MSG. The platform file is composed by two
+hosts called Imnos and Bellevue. Two process are
+implemented in sendrecv.c : sender and receiver.
+Sender process runs on "Imnos" host taking as
+parameter the receiver hostname "Bellevue". Receiver
+process runs on "Bellevue" listening to messages
+from any host.
